updater_check/apply/apply_all/rollback tasks fell through every per-type
branch of the Tasks panel, so they showed the generic custom gear icon, a
raw/truncated command title, and (for the app:'updater' sentinel) a broken
hidden app icon. Wired them in like every other task type:
- tasks-format.js formatCommandForUser PATTERNS: added the 'libreportal updater'
command rows (Apps - Check for Updates / Update All / <App> - Update /
<App> - Roll Back) — only the *self*-update 'libreportal update' was mapped.
- tasks-format.js formatActionTitle: added the updater_* short labels.
- tasks-list-render.js getTaskTypeIcon: updater_check 🔍 / apply ⬆️ /
apply_all ⬆️ / rollback ↩️ (reusing existing verify/update/restore classes).
- tasks-list-render.js renderTaskIcons: treat app:'updater' as a sentinel like
app:'system' so updater_check/apply_all fall back to the LibrePortal logo
instead of a 404'd /core/icons/apps/updater.svg (apply/rollback keep their
real app icon).
node --check clean.
